Abstract
The utility model discloses a bow steering type tractor, of which a front axle and a rear axle are respectively provided with a brake, the brakes of the front and rear axle are respectively connected on brake cylinders which are arranged in parallel, piston rods of two brake cylinders are connected with a brake pedal drive through a brake pushrod device. According to the utility model, the front and rear axle of the tractor is provided with the brake respectively, the brakes of the front and rear axle are respectively controlled by one brake cylinder, two brake cylinders are arranged in parallel to form a brake master cylinder, so that a hydraulic braking system of the tractor comprises two independent hydraulic brake devices, no interference of two brake devices exists, the brake of one of the front axle and the rear axle is in trouble, or one brake cylinder is broken, the other brake device also can be effectively used for braking, thus improving the safety and reliability of the tractor.
Description
Technical field
The utility model relates to a kind of articulated steering formula trac..
Background technology
Advantages such as at present, the braking force owing to hydraulic brake system is big, retro-speed is fast are widely used on the articulated steering formula trac..The patent No. is that 96206103.4 Chinese utility model patent specification sheets discloses a kind of small-sized articulated steering tractor hydraulic brake equipment, this hydraulic brake system is made up of drg, brake pedal, master brake cylinder and brake cylinder that bridge before and after the trac. is provided with respectively, brake pedal promotes master brake cylinder, master brake cylinder is provided with two output circuits, the oil pipe of leading up to directly is connected with the tractor rear axle drg, and another road is connected with the farm tractor front axle drg by brake cylinder.The shortcoming of this hydraulic brake system is if master brake cylinder damages, and then can cause the global failure of trac. brake system, causes the great safety traffic accident of car crash easily.
The utility model content
The purpose of this utility model provides that a kind of drive safety is good, braking reliability high articulated steering formula trac..
The technical solution of the utility model is: a kind of articulated steering formula trac., comprise vehicle frame, vehicle frame is provided with propons and back axle, be respectively equipped with drg on propons and the back axle, be connected with hydraulic brake system on the drg, described hydraulic brake system is mainly by brake pedal, hydraulic braking pump, petrol storage tank and connection oil pipe are formed, described hydraulic braking pump is made up of two brake cylinders that are arranged in parallel, two braking wheel cylinders are in transmission connection by a brake push rod device and described brake pedal, and the output circuits of described two braking wheel cylinders are connected with drg on propons and the back axle by the connection oil pipe respectively.
The input oil circuit of described two brake pumps is connected on the petrol storage tank by connecting oil pipe respectively.
Described two braking wheel cylinders are fixed on the vehicle frame side by side, and an end and the brake pedal of described brake push rod device are connected, and the other end is connected with two piston rods of braking wheel cylinders that are set up in parallel respectively.
The utility model is respectively equipped with drg on the forward and backward bridge of trac., drg on the forward and backward bridge is respectively by a brake cylinder control, two braking wheel cylinders compose in parallel master brake cylinder, make the hydraulic brake system on the trac. form two independent hydraulic brake systems that are provided with, can not interfere with each other between the two cover brake equipments, even the drg that propons or back axle are provided with on one of them breaks down or be that one of them brake cylinder damages, another set of brake equipment also can effectively be braked, and has improved the safety and the reliability of trac..The shared petrol storage tank of two cover brake cylinders can be simplified tractor structure, is convenient to observe the hydraulic pressure oil level simultaneously, prevents to cause braking failure because of oil starvation.
Description of drawings
The structural representation that Fig. 1 implements for the utility model.
The specific embodiment
As shown in Figure 1, the formula trac. of bowing of the present utility model comprises vehicle frame 2, before vehicle frame 2 is provided with, back vehicle bridge 7,8, before, back vehicle bridge 7, be respectively equipped with drg on 8, be connected with hydraulic brake system on each drg respectively, comprising brake pedal 6, this brake pedal 6 is connected with a brake push rod device 5 by connecting rod, one end and the brake pedal of this brake push rod device 5 are connected, its other end is connected to two brake cylinders that are arranged in parallel 3, on 4 the piston rod, two braking wheel cylinders 3,4 output circuit is respectively by before connection oil pipe and the vehicle frame, back axle 7, drg on 8 connects, two braking oil pumps 3, input oil circuit on 4 is connected on each petrol storage tank 1 fixing on the vehicle frame by oil pipe respectively.
Glancing impact, step on brake pedal, this brake pedal produces hydraulic drive power by the piston rod that bonded assembly push rod on it promotes on two brake cylinders that are arranged in parallel 3,4 simultaneously, the output circuit of two braking wheel cylinders 3,4 is delivered to hydraulic thrust on the drg that is provided with on the forward and backward vehicle bridge by connecting oil pipe respectively, in the present embodiment, the output circuit of one of them brake cylinder 3 is connected on the drg that is provided with on the farm tractor front axle 7, and the output circuit of another brake cylinder 4 is connected on the drg that is provided with on the tractor rear axle 8.
The utility model is not limited to the foregoing description, hydraulic braking pump on the trac. is not limited to use the two single-cylinder hydraulic pumps that are arranged in parallel, those skilled in the art is easy to expect that it can also use a kind of master brake cylinder that two twin-tubs in parallel are set to replace means as equivalence in a housing, also can produce identical technique effect.
The utility model can also produce another distortion, and promptly the double pump in parallel that is adopted in the utility model can also be applied to the trac. that back axle is only installed drg, and its two brake cylinders that are arranged in parallel are connected with two drgs on the back axle respectively.
