Abstract

The utility model relates to a tractor, particularly to a recombined tractor formed by improving an ordinary disc type tractor. The utility model is characterized in that the tractor is composed of wheels, a front bumper, a diesel engine, a clutch, a gearbox, a speed reducer, a driving cab, a front axle, a transmission shaft, a tractor frame, a rear axle, a carriage and a vibration damping device, wherein the diesel engine, the clutch, the gearbox and the speed reducer are connected orderly and positioned at a tractor head part, and the tractor head, the driving cab and the carriage are rigidly connected into a whole through the tractor frame. The tractor with the structure has the advantages of high stability of the whole tractor, strong climbing ability and good braking effect. The utility model has a wide market in the countryside.

Description

A kind of trac.

The utility model relates to a kind of trac., specially refers to a kind of trac. that reconfigures that improves through common disc type trac..

At present, the disc type trac. that the agricultural transportation locomotive that China generally adopts in the rural area is a 12-15 horsepower, but there is following weak point in this trac.: (1) head adopts the traction latch to be connected with dragging between the case, the joint, it is bigger particularly to connect the latch load that withstands shocks, because of the latch mop situation idol that causes casualties that comes off that fractures has generation.In addition, the gap, junction is big, head with drag the case amplitude of fluctuation that is in operation bigger, whole vehicle stability is reduced, cause roll-over accident easily.(2) headstock, wheel do not dispose vibration insulating system, and body vibrations is bigger when travelling on unmade way.(3) operator's compartment does not seal, and can't stop wind and rain and dust.(4) front and rear wheel brake mode difference in the braking, one is mechanical braking, and one is compression air brake, is difficult to synchronously, and braking effect is bad.(5) adopt f-w-d, tractive performance is poor, and poor adhesive force when particularly climbing is skidded easily.(6) steering mode is an articulated steering, and the chaufeur health rotates and reverses along with head, turn to not steady, the steering operation difficulty of particularly moveing backward.

The purpose of this utility model is to provide a kind of headstock, operator's compartment, railway carriage to become holistic by the vehicle frame rigid connection, be provided with vibration insulating system, the disc type trac. of closed operator's compartment and back-wheel drive adopts this trac. whole vehicle stability good, hill climbing ability is strong, good braking effect.

Technology contents mainly is: it is made up of front-wheel, front bumper, diesel engine, power-transfer clutch, change speed gear box, retarder, operator's compartment, propons, transmission shaft, vehicle frame, back axle, trailing wheel, railway carriage and shock attenuation unit, wherein diesel engine, power-transfer clutch, change speed gear box, retarder link successively, be positioned at the headstock part, headstock, operator's compartment, railway carriage become as a whole by the vehicle frame rigid attachment.

The advantage of this trac. is: (1) headstock, operator's compartment, railway carriage become an integral body by the vehicle frame rigid attachment, have guaranteed the stability of car load.(2) be provided with shock attenuation unit, further vibration damping.(3) use closed operator's compartment instead, improved driving environment.(4) changing f-w-d is back-wheel drive, the efficient height, and hill climbing ability strengthens.(5) adopt the four-wheel hydraulic brake system, and set up hand brake device, good braking effect.(6) adopt four bar steering hardwarees, turn to flexible, safety.(7) economic, practical.

Description of drawings: Fig. 1 is a car load construction profile scheme drawing of the present utility model;

Fig. 2 is a car load plan structure scheme drawing of the present utility model;

The utility model is implemented by following technical proposals: it is made up of front-wheel [5], front bumper [11], diesel engine [1], power-transfer clutch [2], change speed gear box [3], retarder [4], operator's compartment [13], propons [6], transmission shaft [7], back axle [17], vehicle frame [8], back axle [9], railway carriage [14] and shock attenuation unit, wherein diesel engine [11], power-transfer clutch [2], change speed gear box [3], retarder [4] four link successively, be positioned at the headstock part, headstock, operator's compartment [13], railway carriage [14] become an integral body by vehicle frame [8] rigid attachment.

Diesel engine [1], power-transfer clutch [2] adopt common disc type trac. employed, change speed gear box [3] adopts 130 type automobile gearboxes, adjust the speed of a motor vehicle according to actual needs, other is equipped with a retarder [4], said apparatus has constituted the power pack section of trac., power passes to back axle [9] by transmission shaft [7] and drives trailing wheel [5], thereby trac. is travelled.Operator's compartment of the present utility model is by ceiling, and side door, front window compositions such as [12] are enclosed construction.This trac. has adopted four bar steering hardwarees of automobile, four-wheel hydraulic brake system and hand brake device.Headstock, operator's compartment [13], railway carriage [14] connect with vehicle frame [8] welding respectively becomes an integral body.

For reducing vibration, the utility model is provided with shock attenuation unit, shock attenuation unit between operator's compartment [13] and the vehicle frame [8] is a vibration isolation rubber supporting cushion [10], between front-wheel [5] and the headstock, be provided with the leaf spring vibration insulating system between trailing wheel [17] and the railway carriage [14], form by the shank connection by steel plate [16] and hinge of leaf spring [15].

Claims
