Abstract
The utility model discloses a hydraulic brake caliper structure of an agricultural harvester. The hydraulic brake caliper structure of the agricultural harvester comprises a caliper body and a piston, an inner cavity communicated with an oil inlet hole is arranged inside the caliper body, a piston is arranged in the inner cavity in a matching mode, at the same time an exhaust hole used for exhausting air is arranged inside the inner cavity, and the position of the inlet of the exhaust hole is arranged at the peak of the inner cavity. Due to the modification of the position of the inlet of the exhaust hole, air inside the inner cavity of the caliper is enabled to be exhausted thoroughly, effectiveness of transmission of power of braking oil is ensured, and a pedal is enabled to be lighter, route of the pedal is reduced, and the hydraulic brake caliper structure of the agricultural harvester is good in braking effect.
Description
Technical field
The utility model relates to a kind of hydraulic braking clamp structure of agricultural reaping machine, particularly a kind of agricultural reaping machine.
Background technology
At present, hydraulic braking clamp structure on the market in the agricultural reaping machine all is to be horizontally disposed, as illustrated in fig. 1 and 2, be the schematic diagram of right side hydraulic braking clamp structure, when needing braking, the driver steps on pedal, hydraulic oil by fuel feed hole 1 ' enter clamp inner chamber 2 ', and promotion piston 3 ' make brake(-holder) block hold brake disc tightly, rotate thereby hinder wheel, reach braking effect; And the relieving pedal, piston 3 ' by rectangular loop 4 ' distortion return, piston 3 ' interior contracting makes brake(-holder) block separate with brake disc, removes the braking of tire.
But in the reality, exhaust outlet 21 in the existing clamp structure inner chamber ' entrance location be arranged on whole clamp inner chamber 2 ' the middle part, when carrying out the emptying operation, when the liquid level of hydraulic oil surpasses 21 ' time of exhaust outlet, hydraulic oil also only account for clamp inner chamber 2 ' the bottom, this moment along with hydraulic oil continue be pressed into, hydraulic oil will be along exhaust outlet 21 ' come out, the air that is higher than the inner chamber 2 ' top of exhaust outlet 21 ' entrance location then can't further be discharged, its result cause clamp inner chamber 2 ' in residual all the time air arranged.And the hydraulic drive of clamp mainly is to utilize the Incoercibility of hydraulic oil to carry out transmission of power, in case the air that clamp inner chamber 2 ' middle existence can effectively be compressed in a large number, will have a strong impact on the transmission of power of hydraulic oil, braking strength can reduce, braking effect can be very poor, and can follow the weakness of brake pedal to sink, cause stroke to increase, more serious even can cause skidding malfunctioning, brought very big potential safety hazard for the use of reaping machine.
The utility model content
At the problems referred to above, the utility model has designed a kind of hydraulic braking clamp structure of agricultural reaping machine, it can make the air in the clamp inner chamber thoroughly drain, and has guaranteed the validity of brake fluid transmission of power, makes that pedal force alleviates, pedal travel reduces, good braking effect.
For achieving the above object, the utility model is by the following technical solutions:
A kind of hydraulic braking clamp structure of agricultural reaping machine, comprise caliper body and piston, be provided with the inner chamber of a connection fuel feed hole in the caliper body, be equipped with described piston in the inner chamber, be provided with one simultaneously in the inner chamber for the air vent that drains air, it is characterized in that: described air vent entrance location is arranged on the peak of described inner chamber.
Further, be provided with exhaust bolt in the above-mentioned air vent.
When carrying out the emptying operation, along with being pressed into of hydraulic oil, the liquid level of hydraulic oil constantly rises, air is constantly discharged by air vent, at this, be arranged on the peak of clamp inner chamber because of exhaust outlet entrance location of the present utility model, therefore, have only when the hydraulic oil liquid level in the inner chamber rises to the peak of clamp inner chamber, just have hydraulic oil to come out along exhaust outlet, and this moment, air in the clamp inner chamber is drained fully, thereby guaranteed the emptying validity of clamp inner chambers, made in the brake caliper inner chamber to be full of brake fluid, reached and alleviate pedal force, reduce pedal travel, guarantee the braking effect of reaping machine.
Description of drawings
The schematic diagram of Fig. 1, existing brake caliper structure;
Among Fig. 2, above Fig. 1 A-A to cutaway view;
Fig. 3, structural representation of the present utility model;
Among Fig. 4, the utility model Fig. 3 B-B to cutaway view.
Embodiment
Shown in Fig. 3 and 4, a kind of hydraulic braking clamp structure of agricultural reaping machine, comprise caliper body 1 and piston 2, be provided with the inner chamber 11 of a connection fuel feed hole 111 in the caliper body 1, be equipped with described piston 2 in the inner chamber 11, inner chamber 11 peak positions are provided with one for the air vent 112 that drains air simultaneously.
In the described air vent 112 exhaust bolt 113 is being set, exhaust bolt 113 pulls out when emptying is operated air vent 112 is in communication with the outside, and inserts again air vent 112 is blocked fully behind the emptying EO.
When carrying out the emptying operation, along with hydraulic oil is pressed into by fuel feed hole 111, the liquid level of hydraulic oil constantly rises in the clamp inner chamber 11, thereby force in the clamp inner chamber 11 air constantly to be discharged by air vent 112, at this, be arranged on the peak of clamp inner chamber 11 because of exhaust outlet of the present utility model 112 positions, have only when the hydraulic oil liquid level in the inner chamber 11 rises to the peak of clamp inner chamber 11, just there is hydraulic oil to come out along exhaust outlet 112, and this moment, air in the clamp inner chamber 11 is drained fully, thereby guaranteed the emptying validity of clamp inner chamber 11, make in the brake caliper inner chamber 11 to be full of brake fluid, reach and alleviate pedal force, reduce pedal travel, guarantee the braking effect of reaping machine.
The above, it only is preferred embodiments of the present utility model, be not that the utility model is done any pro forma restriction, every foundation know-why of the present utility model still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations or modification that above embodiment does.
Claims (2)
1. the hydraulic braking clamp structure of an agricultural reaping machine, comprise caliper body and piston, be provided with the inner chamber of a connection fuel feed hole in the caliper body, be equipped with described piston in the inner chamber, be provided with one simultaneously in the inner chamber for the air vent that drains air, it is characterized in that: described air vent entrance location is arranged on the peak of described inner chamber.
