The hydraulic motor is a directional crankshaft radial plunger type motor without a connecting rod; the motor can transform the energy of working pressure oil into the rotating mechanical energy of a crankshaft for driving an external load to work; and an eccentric shaft and a five-piston or multi-piston structure with relatively low vibration frequency are used. The throttle is disposed on a hydraulic pipeline, and composed of a throttle valve which is in a knob type or switch type structure. The hydraulic retarder for vehicles of the utility model has the advantage of simple structure, low cost and good use effect.
Description
Technical field
The utility model relates to the automotive safety technical field, particularly a kind of vehicle hydrodynamic retarder.
Background technology
At present, the quantity that China's passenger and freight car is installed all kinds of retarders increases (comprising engine exhaust and brake, vehicle hydrodynamic retarder, current vortex retarder) fast, and engine exhaust is closed assist brake, be mainly used in big discharge capacity imported car, on dilly, there is not any braking effect, the float amount truck passenger vehicle that incompatibility China is more general has injury to driving engine again; Vehicle respectively has characteristics with hydrodynamic retarder and two kinds of products of current vortex retarder, vehicle performance there are the road conditions of specific (special) requirements at some, particularly run specially in the highway section, mountain area, the performance of current vortex retarder can't be competent fully, situations such as very how continuous down-hill route or carriage of dangerous goods are arranged, current vortex retarder is along with work-hours prolongs, in minutes operating temperature just can reach more than hundreds of degree, and along with the rising of temperature, slow effect also descends fast, current vortex retarder through the condition of high temperature work of being everlasting not only produces very large influence to change-speed box, and self also is subjected to very large influence in the life-span.Under the usage condition of harshness, will change a new retarder about 2 years; Simultaneously, because the working current of current vortex retarder is very big, the heavy-current discharge of 100~150A makes the very fast damage of storage battery, and the significant magnetic field that produces during current vortex work also has very large electromagnetic interference to the electric equipment on the car.Since the inadequate natural endowment of the usefulness that current vortex retarder characteristic aspect works long hours at retarder, and bigger than the hydrodynamic retarder deadweight, caused the inclination of market to hydrodynamic retarder.
The vehicle hydrodynamic retarder is a kind of employing rotary damping device, utilize oil to realize that at rotor and stator interphase interaction power vehicle is slow, play the effect of auxiliary braking, mainly be used in full size vehicle, the heavily card big as discharge capacity, because the vehicle big no friction of hydrodynamic retarder braking torque force, there is not the braking heat of continuing decline, but the vehicle hydrodynamic retarder on the existing market, price is higher, and the structure more complicated, manufacturing technology and accuracy requirement are higher.
The utility model content
The purpose of this utility model is exactly in order to solve the deficiency of prior art, and provide a kind of simple in structure, the vehicle hydrodynamic retarder that cost is low, result of use is good.
The utility model is to adopt following technical solution to realize above-mentioned purpose:
A kind of vehicle hydrodynamic retarder is arranged on the vehicle, mainly is made of HM Hydraulic Motor, it is characterized in that: described vehicle also comprises and HM Hydraulic Motor bonded assembly hydraulic pipe, air restrictor and hydraulic reservoir with hydrodynamic retarder; Described hydraulic motor output shaft is arranged on Vehicle Transmission Bridge or superimposed trailer axletree or the Automotive transmission, and is connected with the output shaft of Transmission Bridge or axletree or Automotive transmission.
Described HM Hydraulic Motor is that directed bent axle does not have connecting rod radial plunger type motor, the energy of operation pressure oil can be changed into the rotating mechanical energy of bent axle, drives the outer lotus work of loading with, and adopts five piston mechanisms or many piston mechanisms of eccentric shaft and low vibration frequency.
Described and oil outlet hydraulic pipe bonded assembly HM Hydraulic Motor is arranged on top, and oil inlet is arranged on the bottom, and output shaft is arranged on sidepiece.
Described air restrictor is arranged on the hydraulic tubing, comprises flow regulating valve; This flow regulating valve is a rotor switch formula structure.
The beneficial effect that the utility model enforcement such scheme can reach is:
One, the utility model vehicle is simple with hydraulic speed buffer structure, and is in light weight, and it is little to take up room, and cost is low; Effective guard rows vehicle brake, the brake strap that passenger vehicle is heavily blocked etc. prolongs more than 8 times service life, bears in the vehicle traveling process 90% brake; reduce the gearshift number of times, can saving fuel, and can improve average ground speed; save haulage time, thereby reduce operating cost.
Two, by being connected with the automobile water-cooling system, can solve the heat cooling in the slow process quickly and effectively, operating temperature is not high, brake torque is big, does not have the friction operation, low noise, low-speed stability is good, has fully guaranteed traffic safety, and use effect on heavy duty truck is more obvious.
