Abstract
The present invention relates to a hinge tractor with a hydraulic drive device on rear wheels. The present invention is additionally provided with a hydraulic drive device on a rear axle of the existing hinge tractor trailer, wherein the existing hinge tractor trailer comprises front wheels (1), a machine head (2), a trailer (5), a rear wheel shaft (6) and a hydraulic lifting device composed of an oil pressure pump (3), an oil tank (4), a valve-1 (11), a valve-2 (8) and a pipeline; the hydraulic drive device is composed of an oil motor (7), a one-way valve (10), a valve-3 (12) and a pipeline (13); the hydraulic drive device directly drives the rear wheel shaft (6) of the tractor trailer. When the present invention runs on a flat road, the hydraulic drive device is not started to work, the tractor is made to use front wheels to drive, and the advantages of an original hinge tractor can be kept; when the present invention runs on a road surface which has big slope and needs climbing, the hydraulic drive device is started to work, when the front wheels drive, the rear wheels also become drive wheels simultaneously, and the tractor becomes a four-wheel drive tractor. The tractor keeps the advantages of an original hinge tractor, and also improves the climbing capacity; the present invention avoids the slipping phenomenon when running on slope, and is suitable for running on road surfaces, such as a flat road, a mountain road and a road having big slope.
Description
[technical field]
The present invention is a kind of trac., is the frame-steered tractor that a kind of trailing wheel is provided with fluid pressure drive device specifically.
[background technology]
At present, the frame-steered tractor of production and selling in all parts of the country, for example common 12Y trac. is to be fused by head and the trailer articulated mounting by the centre, by the f-w-d of head, the articulated mounting by the centre drags/promotes trailer railway carriage forward/backward during walking.Because the size of propulsive effort mainly decides by head and ground-surface friction force size, and equaling the weight of head, friction force multiply by ground-surface friction coefficient, friction coefficient one regularly, the weight of head is big more, the friction force that produces is just big more, but the weight of common trac. head is unmodified, and therefore the trac. hill climbing ability of this structure is poor, as long as the goods of adorning on the trailer is heavy slightly or meet the rainy day, during climbing skidding will appear.
[summary of the invention]
Poor in order to overcome existing frame-steered tractor hill climbing ability, the defective of skidding easily, it is strong to the invention provides a kind of hill climbing ability, load-carrying or non-slip frame-steered tractor when rainy.
For solving its technical matters, the technical solution used in the present invention is: on the basis of existing common radial type 12Y trac., set up the device of a cover hydraulic driven trailer trailing wheel.This device is that the hydraulic pressure with existing 12Y tractor hydraulic pump can be propulsion source, by valve and plumbing connection on the HM Hydraulic Motor that is located on the trailer back axle wheel shaft, start valve, hydraulic pressure can be by the wheel shaft rotation of fluid motor-driven trailer back axle, advance thereby drive trailer wheels, reach the purpose of four wheel drive.
The invention has the beneficial effects as follows: 1. because the present invention is improved on the basis of existing radial type 12Y tractor structure, do not change the structure of former trac., therefore it to have kept original frame-steered tractor simple in structure, maneuvering performance is good, the advantage that turn radius is little.2. owing on the wheel shaft of trailer back axle, set up fluid pressure drive device, when trac. in that road gradient is big when needing climbing, in f-w-d, the work of primer fluid pressure device, making trailing wheel is that trailer wheel also becomes drive wheel, form the structure of four wheel drive, so it has strengthened hill climbing ability, skidding in the time of avoiding going up a slope has improved the traction adhesion value of trac.; Improve load carrying ability and road speed when trac. is climbed, thereby improved the work efficiency of trac..3. simple in structure, easy to operate because of set fluid pressure drive device, cost is low, can comprise the road surface cruising that the gradient is big on various road surfaces during work, can increase the driving profit for the car owner, and is easy to utilize.
[description of drawings]
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a fluid pressure drive device structural representation of the present invention.
Among the figure: 1 trac. front-wheel, 2 trac. heads, 3 hydraulic oil pumps, 4 hydraulic reservoirs, 5 trailers, 6 trailer trailing wheels, 7 HM Hydraulic Motor, 8 valves-2,9 hydraulic ram, 10 check valves, 11 valves-1,12 valve-3,13 pipeline.
[specific embodiment]
