Problems solved by technology

[0002] The current engineering vehicles such as wheeled excavators, in the driving state such as driving, parking, acceleration, deceleration, etc., the driver and the operator need to make corresponding operations in time and control the size of the accelerator to adapt to the changes in the driving state. It is also necessary to perform corresponding operations such as shifting gears, adjusting the steering wheel, etc., which is not only inconvenient to operate, but also requires further improvement in operability
[0003] In the case of complex road conditions and harsh working environments, this will bring great inconvenience to drivers and operators, and even affect safe production.

Embodiment 1

[0052] Such as Figure 1 to Figure 11 As shown, in this embodiment, the combined accelerator and travel control valve assembly mainly includes a pedal mounting seat 100 , a pedal body 200 , and a combined accelerator and travel control valve 300 .

[0053] The throttle and travel control combined valve 300 mainly includes a throttle control device 400 , a travel control combined valve 500 , and a travel direction control solenoid valve 600 .

[0054]The throttle control device 400 mainly includes a reset mechanism and a throttle opening control mechanism 420 .

[0055] The travel control combination valve 500 mainly includes an outer valve body 510 , a combination valve core 512 , a combination return spring 513 and a combination valve control part 514 .

[0056] The traveling direction control solenoid valve 600 mainly includes a solenoid valve body 610, a solenoid valve core 620, an electromagnetic return spring 624 and a solenoid valve control part.

[0057] Preferably, t...

Embodiment 2

[0109] This embodiment also includes an inner valve body 511 , the inner valve body 511 is located in the combined spool chamber 510 b, and the other free end of the outer return spring 5131 pushes against the inner valve body 511 . Through the inner valve body 511, the combination valve oil inlet cavity 510a, the combination valve core cavity 510b, the combination valve distribution cavity 510c and the combination valve oil return cavity 510d can be communicated.

[0110] Preferably, the top of the inner valve body 511 is provided with an inner valve body through hole 5123a adapted to the inner valve core 5122, and the inner valve core lower boss 5122e of the inner valve core 5122 extends into the inner valve body 511, and the inner valve core 5122 The concave part of the inner valve core of the core 5122 and the upper boss 5122d of the inner valve core can freely pass through the through hole 5123a of the inner valve body. When the inner spool 5122 moves down to the working ...

Abstract

The throttle and walking control combination valve assembly disclosed by the present invention includes an accelerator control pedal assembly for controlling the throttle opening of the engine, a walking control combination valve for controlling the advance and retreat speed, and a walking direction control solenoid valve for controlling the walking direction; the three are as follows Configuration: When the travel direction control solenoid valve is switched to the advance and retreat state, the throttle opening changes in direct proportion to the flow rate of the hydraulic fluid connected to the travel related mechanism through the travel control combination valve. In the present invention, in the state of driving acceleration and deceleration, the operator only needs to step on the control part of the combined valve to realize the larger the opening of the accelerator, the more oil supplied to the hydraulic traveling system, and the faster the vehicle speed. The car can enter, retreat and neutral when the power is on; this more humanized control method can adapt to the driving habits of drivers and workers, and brings great convenience; it is especially suitable for operations in complex road conditions and harsh operating environments, and can be further improved Improve the comfort and safety of driving and working.

Description

technical field [0001] The invention relates to a pedal of an engineering vehicle such as a wheeled excavator, in particular to an accelerator and travel control combined valve assembly. Background technique [0002] The current engineering vehicles such as wheeled excavators, in the driving state such as driving, parking, acceleration, deceleration, etc., the driver and the operator need to make corresponding operations in time and control the size of the accelerator to adapt to the changes in the driving state. Also need to do corresponding operation to hang gear, adjust steering wheel etc., not only inconvenient to operate, and operability also needs to be further improved. [0003] In the case of complicated road conditions and bad working environment, this brings great inconvenience to drivers and operators, and even affects safe production. [0004] Therefore, in view of the inconvenient operation of engineering vehicles such as wheeled excavators, it is necessary to ...
