Abstract
The utility model discloses a hydraulic walking device of motor sweeper, it includes that front wheel drive device and rear wheel turn to the device, the front wheel drive device comprises left and right two the same front wheel drive units, the front wheel drive unit includes hydraulic motor, drum brake and wheel, wherein, hydraulic motor's drive shaft and drum brake's brake rim and the wheel connection. The utility model discloses a can the accurate control speed of a motor vehicle to hydraulic motor flow of control, above -mentioned design makes the utility model discloses hydraulic walking device has advantages such as simple structure compactness, control convenience, response speed piece and reliability height, additionally, the utility model discloses a rear wheel is realized turning to, has less turning radius for the motor sweeper can adapt to different environment's work.
Description
Technical field
The utility model relates to a kind of pickup sweeper parts, is specifically related to a kind of hydraulic walking device of pickup sweeper.
Background technology
Pickup sweeper of the prior art, its driving system comprises the parts such as power-transfer clutch, change-speed box, transmission shaft, main reduction gear, diff and semiaxis.The power that driving engine exports first through power-transfer clutch, by power-transfer clutch become turn round with speed change after, through transmission shaft transmission of power on main reduction gear, finally by diff and semiaxis by transmission of power on drive wheel.The pickup sweeper of current use, its drive form is preposition forerunner's mode, and this kind of type of drive is due to engine power use semiaxis Direct driver front-wheel after diff, and do not need through transmission shaft, kinetic equation loss is less; But, because front-wheel is responsible for driving and turning to simultaneously, so Turning radius is comparatively large, easily there is the problem of understeer.In addition, above-mentioned type of drive has the shortcomings such as complex structure, speed of response be delayed.
Utility model content
The purpose of this utility model is the hydraulic walking device proposing a kind of pickup sweeper, and it adopts following technical scheme:
The hydraulic walking device of pickup sweeper, comprises front-wheel drive and apparatus for rear wheel steering, and front-wheel drive is made up of left and right two identical front wheel drive unit; Described front wheel drive unit comprises HM Hydraulic Motor, drum brake mechanism and wheel; Wherein, the axle drive shaft of HM Hydraulic Motor is connected with the brake drum of drum brake mechanism and wheel.
Preferably, described front wheel drive unit also comprises HM Hydraulic Motor permanent seat, and this HM Hydraulic Motor permanent seat is connected in the frame of pickup sweeper by flange.
Preferably, described apparatus for rear wheel steering left and right two trailing wheels of comprising back axle and being connected with described back axle; Back axle is provided with the steering hardware be connected with two trailing wheels.
The utility model tool has the following advantages:
The hydraulic walking device of the pickup sweeper that the utility model is addressed, it comprises front-wheel drive and apparatus for rear wheel steering, wherein, front-wheel drive comprises two identical front wheel drive unit, front wheel drive unit adopts fluid motor-driven front-drive, by can accurate regulation speed to the control of HM Hydraulic Motor flow; Above-mentioned design makes the utility model hydraulic walking device have simple and compact for structure, control convenience, speed of response block and high reliability; In addition, the utility model realizes turning to by trailing wheel, has less Turning radius, makes pickup sweeper can adapt to the work of varying environment.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail:
Shown in composition graphs 1, the hydraulic walking device of pickup sweeper, comprises front-wheel drive 1 and back wheel driving gear 2.Be beneficial to by the two the f-w-d and rear-axle steering function that realize pickup sweeper, improve the Applicable scope of pickup sweeper.
Front-wheel drive 1 is made up of left and right two identical front wheel drive unit 3.Concrete,
As shown in Figure 2, front wheel drive unit 3 comprises HM Hydraulic Motor 4, drum brake mechanism and wheel 5.Wherein, the axle drive shaft of HM Hydraulic Motor 4 is connected with the brake drum 6 of drum brake mechanism and wheel 5.
The driving engine of pickup sweeper is connected with HM Hydraulic Motor 4, and hydraulic control motor 4 drives wheel 5 to rotate.This kind of type of drive tool has the following advantages: the speed of a motor vehicle increases with the flow increase of HM Hydraulic Motor 4, and fast response time, control are conveniently.
In addition, conveniently fixed hydraulic motor 4, front wheel drive unit also comprises HM Hydraulic Motor permanent seat 7, (not shown) in this HM Hydraulic Motor permanent seat 7 is connected to pickup sweeper frame by flange 8.
As shown in Figure 3, apparatus for rear wheel steering left and right two trailing wheels 10,11 of comprising back axle 9 and being connected with back axle 9; Back axle 9 is provided with the steering hardware 12 be connected with two trailing wheels 10,11.
Steering hardware 12 with reference to steering hardware existing in prior art, no longer can be described in detail herein.
Certainly; more than illustrate and be only preferred embodiment of the present utility model; the utility model is not limited to enumerate above-described embodiment; should be noted that; any those of ordinary skill in the art are under the instruction of this specification sheets; made all equivalently to substitute, obvious form of distortion, within the essential scope all dropping on this specification sheets, protection of the present utility model ought to be subject to.
