A release device for a polar profile observation system includes a support frame, a release base, a control electronic cabin, a release mechanism, and a floating body. The support frame performs an up and down profile movement along the under-ice guide cable, and is bonded with the profile observation system before the profile observation system is released. The release base is configured to provide an installation platform for the release mechanism. The control electronic cabin is configured to receive a release signal sent by the profile observation system and enable the release mechanism. The release mechanism is configured to perform a release task, so that the profile observation system can be detached from the support frame. The floating body provides buoyancy to balance the gravity of the release device.

A hybrid power train structure for off-road vehicles (ATVs, UTVs and SSVs) uses an internal combustion engine ('ICE') rotating a crankshaft through a continuously variable transmission (“CVT”) as a primary source of locomotion torque, but also includes a driving/generator motor which, in certain established conditions, can either provide an additional or alternative source of locomotion torque or can harvest electricity from the torque created by the internal combustion engine. The driving/generator motor is an axial flux motor of small size for its relative torque output, which can either be directly coupled to the CVT output shaft or, when additionally used as a starter motor for the ICE in an automatic ICE starting and stopping routine.

An outer ring of an inner joint of the constant speed transmission shaft is provided with a vehicle speed sensor rotating synchronously with the inner joint, and the drive axle is fixedly equipped with a signal collecting device opposite to the vehicle speed sensor and configured to monitor a rotation speed signal of the vehicle speed sensor. The inner joint of the constant speed transmission shaft transmits torque during the running of a vehicle, and through monitoring a rotation speed of the inner joint, the rotation data of rear wheels can be obtained. By mounting the vehicle speed sensor on the inner joint and fixing the signal collecting device on the drive axle for monitoring the rotation speed signal of the vehicle speed sensor, the signal reading is stable, which facilitates the maintenance, reduces the cost, and can satisfy the environmental requirements.

A constant velocity ball joint uses a star shaped sleeve with a splined connection to its shaft. The sleeve is longitudinally retained on its shaft using a retaining ring in an outwardly facing groove of the shaft. The star shaped sleeve has a 30&#xb0; assembly assist chamfer angle on one side, as well as a 45&#xb0; transition chamfer angle and a 65&#xb0; ramp chamfer angle facing the opposite direction. These angles control the diameter of the retaining ring as it is compressed inward into the groove during assembly and disassembly. The star shaped sleeve can be used in a dynamic length CV joint, with the splines of a configuration that allows longitudinal sliding of the sleeve on the shaft, so the shell of the dynamic length CV joint still can be of the spherical race type.

A type of constant velocity universal joint has the spline slip structure, including the steel wire retaining ring and the star-shaped sleeve which are both mounted on a common axis, and the steel wire retaining ring limiting device. The said steel wire retaining ring limiting device is a groove arranged on the said star-shaped sleeve and used for holding the said steel wire retaining ring. The said steel wire retaining ring may be elliptic or circular. The movement in the radial direction of the steel wire retaining ring will be limited by the groove on the star shaped sleeve and there occurs a certain contraction, in addition to appropriate the chamfer angle of the groove, when removing the spline shaft from the star-shaped sleeve.

A mechanical locking differential includes a driving ring in a differential housing between right and left active components. The driving ring is in line with the input bevel gear. The differential housing has a thin wall in a single, integral shell around the driving ring. Several hollow cylindrical shaft pins are used to attached the driving ring to the differential housing, with the shaft pins being driven radially relative to the transverse axis of the differential outputs in an interference fit with the housing and the driving ring. The shaft pins are held from axially backing out by two small rivets. The shaft pins preferably have a threaded inner diameter which assists in removal. The shaft pin attachment allows the bevel gear to extend closer to the transverse axis without obstruction.
