Abstract

The invention relates to mechanical structure design and discloses an elastic device for being in parallel connection with a hydrodynamic retarder. Part structure optimization design is adopted, and the elastic device aims at solving the problem that in the hydrodynamic retarder, after multiple parts such as an output shaft, a conical roller bearing, a retarder cover, a stator and a bearing race are assembled, tolerance accumulation is formed; an annular workpiece designed through elastic automatic adjustment is adopted for eliminating the tolerance; in addition, a traditional gasket is replaced for adjusting the free gap of a conical bearing; the problem that when the gasket is used for adjusting the free gap of the conical bearing, assembling difficulty is great, so that the free gap of the conical bearing is inconsistent in size is solved; the service life of the conical bearing is prolonged; meanwhile, the service life of the retarder is also prolonged; and safety of vehicle travelling is guaranteed more.

Description

technical field [0001] The invention relates to mechanical structure design, in particular to an elastic device for a parallel hydraulic retarder. Background technique [0002] Hydraulic retarder is also called hydraulic deceleration device. Cars use exhaust brake when going down a long slope. Although they can receive a good braking effect, for heavy vehicles with a larger tonnage, the exhaust brake effect is limited. Therefore, hydraulic deceleration retarders are installed on heavy vehicles equipped with hydromechanical transmission. [0003] The hydraulic retarder adopts the principle of hydraulic power. It includes a working chamber, an oil storage chamber and a cooler. A pair of stator impellers and rotor impellers are sealed in the working chamber. The rotor impeller is linked with the vehicle power shaft. There are vanes on the top, and the working chamber is connected with the oil storage chamber. When braking is required, the control device sends a signal, and th...
