Abstract
A full hydraulic steering axle for tractor is composed of a disc brake, a disc brake disc and a steering straight pull rod. The disc brake is provided at the front end of the left part of the disc brake disc which is provided symmetrically. The left end and the right end are provided with a steering wheel housing. Two steering joints are respectively supported by a bearing and is provided in an inner chamber which is formed by the disc brake disc and the steering wheel housing. End caps are provided at the outer ends for sealing. Two inner ends are positioned by a main shaft pin and are connected with a front axle of the automobile. The inner lower pull arm holes of two steering joints are connected with a steering straight pull rod. The left end of an oscillating transverse cylinder is connected with the front axle of the automobile. The right end is connected with the inner lower pull arm hole of the right steering joint. The utility model adopts the general component of automobile and has the advantages of mature technique, sufficient supplement of component and low cost. The full hydraulic steering axle prevents the using of a power steering device, and further has the advantages of: large structural space, convenient cylinder replacement and oil seal maintenance, more convenient steering, and better operation comfort.
Description
Technical field
The utility model relates to tractor truck, particularly relates to a kind of 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
The purpose of this utility model will provide a kind of tractor truck hydro-steering bridge exactly, and it can overcome the existing defective of above product well.The purpose of this utility model is to realize like this, a kind of 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 automobile front axle, 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 automobile front axle, 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 utility model 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 the utility model structural representation;
Fig. 2 is the part sectional view in the utility model structural representation;
1. disc brake, 2. automobile front axle, 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 utility model is described in further detail below in conjunction with accompanying drawing;
A kind of 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 automobile front axle 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 automobile front axle 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.
