Embodiment 1

[0034] refer to Figure 1-8 As shown in the figure, the input shaft 1 is connected to the power of the vehicle transmission system; it realizes its own rotation with the energy of the power system. In order to reasonably adjust the rotation speed on the input shaft 1 to achieve the rotation speed of the retarder that meets the actual requirements, a speed-increasing and torque-reducing gear can be used. And other mechanisms transfer the output speed of the power system gearbox to the input shaft 1 of the retarder through conversion.

[0035] The retarder structure includes an input shaft 1, a bearing 2, an oil seal 3, a casing assembly, a rotor assembly and a clearance control assembly; the casing assembly is provided with an oil inlet and an oil outlet for inputting and outputting oil, and also includes The front housing 6, the middle housing 9 and the rear housing 10 are assembled and detachably connected in sequence from front to back; the rotor assembly includes the ring g...

Embodiment 2

[0045] On the basis of Embodiment 1, the oil distribution pans of the present invention can be set into two groups, including the front oil distribution pan 5 and the rear oil distribution pan 13. The working principles of the two are the same. On the oil pan, the position between the oil distribution pan and the rotor assembly is adjusted to realize the adjustment of the end-to-end clearance and to achieve accurate control of the braking pressure.

[0046] The mechanism can be installed in series or parallel arrangement after the gearbox.

Abstract

The invention discloses a planet wheel type high-viscosity oil medium high-pressure retarder. A power input shaft of the retarder is connected with a transmission shaft of a gearbox through a speed-increasing and torque-reducing gear, under the driving of the torque of the transmission shaft, a mechanical structure generates rotational motion in a cavity of the retarder, pressure change drives liquid in the cavity to circularly flow, the liquid is sucked in by an oil suction cavity and compressed in an output cavity through a sealing belt, and kinetic energy of a vehicle is converted into pressure energy of a medium; the braking force is in direct proportion to the single-rotation pump quantity and the pressure difference between the oil inlet cavity and the oil outlet cavity, and the vehicle retarding function is achieved. Vehicle transmission torque is directly intervened through hydraulic pressure, the response speed is high, a mechanical mechanism is compact and simple, and the overall size and weight are small.

Description

technical field [0001] The invention relates to the technical field of hydraulic retarders, in particular to a planetary wheel type high-viscosity oil medium high-pressure retarder. Background technique [0002] There are many road intersections in urban areas, dense bus stops and large passenger flow, and buses often have to brake frequently; the roads in mountainous areas are steep and there are many sharp bends, and medium and large trucks and buses that travel in mountainous areas for a long time also often need to brake. In the case of long-term and frequent operation of the brake, it will cause rapid wear of the brake shoes, short service life of the brake pads, and loss of braking force or sharp decline in braking performance due to the thermal recession of the brake, which has also become the main cause of traffic accidents. Therefore, it is necessary to have an auxiliary braking system. [0003] As an auxiliary braking component of the vehicle, the retarder reduces...
