Abstract
The invention relates to a full-hydraulic steering axle for a tractor, which comprises a disc brake, a disc type brake disc and a steering drag link, wherein the disc brake is arranged at the front end on the left side of the disc type brake disc symmetrically arranged, and steering wheel housings are arranged at the left end and the right end; two steering knuckles are respectively arranged in an inner cavity formed by the disc type brake disc and the steering wheel housings through bearing supports, the outer ends are sealed through end covers, two inner ends are positioned by a main shaft pin and connected with a general-purpose automobile front axle, and pulling arm holes at the lower inner ends of the two steering knuckles are connected with the steering drag link; and the left end of an oscillating horizontal oil cylinder is connected with the general-purpose automobile front axle, and the right end is connected with the pulling arm hole at the lower inner end of the steering knuckle at the right end. Automobile general-purpose parts are adopted in the full-hydraulic steering axle for the tractor, the technology is mature, the supply of accessories is sufficient, and the cost is low. The full-hydraulic steering axle can avoid using a power steering device, the structural space is spacious, the replacement of the oil cylinder and the maintenance of an oil seal are convenient, the steering is more lightweight and the comfortableness of the operation is better.
Description
Technical field: the present invention relates to tractor truck, particularly relate to tractor truck hydro-steering bridge.
Background technology: present domestic tractor truck all adopts bridge construction behind the similar fork truck with steeraxle, and this structure is used for existing on the tractor truck certain defective.Mainly contain the following aspects:
One. is zero with steeraxle owing to the fork truck operating mode has determined this steeraxle toe-in with tonnage level fork truck, and need not adjust between the connector, reaches 30KM/H for the tractor truck speed of a motor vehicle.Even bigger, it is irrational that toe-in can not be adjusted.
Two. the difficult control of steering trapezium, only speed-adaptive is less than the 10KM/H vehicle.
Three. the oil cylinder piston oil sealing occurs and damage, need during replacing oil cylinder is unloaded, finished by four bolts and two locating dowel pins and oil cylinder and pontic are fixing, the mounting or dismounting work capacity is big, maintenance difficult.
Four. because toe-in of front wheel can not be adjusted, cause wear on tyres fast.
Summary of the invention; Purpose of the present invention will provide a kind of tractor truck hydro-steering bridge exactly, and it can overcome the existing defective of above product well.The object of the present invention is achieved like this, tractor truck hydro-steering bridge, be made up of disc brake, disc type brake dish, steering drag link, it is characterized in that: the left side front end of symmetrically arranged disc type brake dish is provided with disc brake, and two ends, the left and right sides are provided with and turn to hub; Two steering swivels are arranged in disc type brake dish and the inner chamber that the wheel flutter hull shape becomes by bearing supporting respectively, and there is end cap seal the outer end, and two the inners are located by swirl pin and are connected with the General Motors propons, and the interior lower end drawing arm hole of two steering swivels is connected with steering drag link; Oscillating type transverse hydro-cylinder left end is connected with the General Motors propons, and right-hand member is connected with the interior lower end drawing arm hole of the steering swivel of right-hand member, and described oscillating type transverse hydro-cylinder is provided with transverse hydro-cylinder and imports and exports joint.The present invention adopts the automobile common component, and technology maturation, fittings supply abundance, cost are low.The hydro-steering bridge has been avoided the use of power-assisted steering device, and structure space is free from worry, and it is easy to maintenance to change the oil cylinder oil sealing, turns to lightlyer, and operation comfort is better.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the part sectional view in the structural representation of the present invention;
1. disc brake, 2. General Motors propons, 3. disc type brake dish, 4. oscillating type transverse hydro-cylinder, 5. transverse hydro-cylinder is imported and exported joint, 6. steering drag link, 7. steering swivel 8. turns to hub.
The specific embodiment: the invention will be further described below in conjunction with accompanying drawing;
Tractor truck hydro-steering bridge is made up of disc brake 1, disc type brake dish 3, steering drag link 6, and it is characterized in that: the left side front end of symmetrically arranged disc type brake dish 3 is provided with disc brake 1, and two ends, the left and right sides are provided with and turn to hub 8; Two steering swivels 7 are arranged in disc type brake dish 3 and the inner chamber that turns to hub 8 to form by bearing supporting respectively, and there is end cap seal the outer end, and two the inners are located by swirl pin and are connected with General Motors propons 2, and the interior lower end drawing arm hole of two steering swivels 7 is connected with steering drag link 6; Oscillating type transverse hydro-cylinder 4 left ends are connected with General Motors propons 2, and right-hand member is connected with the interior lower end drawing arm hole of the steering swivel 7 of right-hand member, and described oscillating type transverse hydro-cylinder 4 is provided with transverse hydro-cylinder and imports and exports joint 5.During concrete enforcement, steeraxle adopts automobile front axle, makes steering side tube into the oscillating type transverse hydro-cylinder, and oil cylinder is set to the swing form, and simple, the bearing circle operation is lighter, simple in structure.To draw car different with the applying working condition of fork truck owing to involve, and steering trapezium and front and back are restrainted and will often be adjusted, and can avoid the steering tire heel and toe wear.According to customer requirements, can match two kinds of braking models of drum brake and disc type.Hydro-steering provides power oil by driving engine driven gear pump, turns to lightlyer, and operation comfort is better.
