Description

A hydraulically driven crawler-type walking chassis

technical field

The utility model relates to a walking machine technology, in particular to a hydraulically driven crawler-type walking chassis.

Background technique

At present, most of the vehicle chassis are wheeled and crawler-type, especially agricultural machinery mostly adopts wheeled walking chassis, because the wheel-driven walking chassis has simple structure, convenient control and high driving speed. However, for muddy and soft fields or hills and mountains with a certain slope, more crawler-type walking chassis are used, especially hydraulically driven crawler-type walking chassis. powerful. Most of the existing crawler chassis adopt metal crawlers, which are high in cost, heavy in weight and cause great damage to the ground, which is not conducive to walking and transportation.

Contents of the invention

In order to overcome the deficiencies and defects in the prior art, the purpose of this utility model is to provide a hydraulically driven crawler-type walking chassis, which can solve the problem of walking on soft roads or mountains.

The utility model is realized through the following technical solutions:

The utility model is a crawler-type walking chassis driven by hydraulic pressure. The machine is composed of a vehicle frame, a rubber crawler, a guide wheel, a supporting wheel, a supporting wheel, a driving wheel, a baffle, a hydraulic motor and a speed detection disk. The frame is equipped with guide wheels, supporting rollers, supporting pulleys and driving wheels; the baffle is installed on both sides of the supporting wheels; the hydraulic motor is installed at the rear end of the frame, and the driving wheel connected; the speed detection disc is installed on the drive wheel and rotates synchronously with the drive wheel.

It is characterized by:

The vehicle frame is a side beam structure, which is composed of two longitudinal beams and two cross beams. In order to increase the load-bearing capacity of the vehicle frame, the cross beam adopts a U-shaped structure and connects the two longitudinal beams. In order to facilitate the installation of other devices on the vehicle frame, the two beams extend forward and backward respectively to form a sub-frame.

The guide wheels, supporting rollers, supporting pulleys and driving wheels are installed on two longitudinal beams of the vehicle frame. The baffles are installed on both sides of the supporting wheels and connected with the longitudinal beams of the vehicle frame to prevent debris from winding on the supporting wheels and play a protective role.

The rubber crawler track is a seamless integral design, the walking resistance is about 15% smaller than that of ordinary metal track, and it has a vibration absorption effect, which can reduce the vibration of the machine and prolong the service life of the machine. The middle part of the track is thick, and the structural design of the two sides gradually becomes thinner, which makes the steering more flexible. The use of rubber tracks can improve the driving performance of agricultural machinery, construction machinery and other machinery. Rubber tracks can improve the form and performance of machinery, and are of great significance for expanding the operation and transportation of soft ground such as farmland, deserts, and swamps.

The hydraulic motor is installed on the vehicle frame and connected with the driving wheel, and the hydraulic motor provides power for the whole machine to travel and provides sufficient torque and rotation speed.

The rotating speed detection disk is installed on the driving wheel and rotates synchronously with the driving wheel.

Fig. 1 and Fig. 2 are the overall layout plans of a hydraulically driven crawler-type walking chassis of the utility model.

detailed description

Below in conjunction with accompanying drawing 1 and Fig. 2 the utility model is described further:

The technical solution adopted by the utility model to solve the technical problems is a hydraulically driven crawler-type walking chassis, including a vehicle frame 1, a rubber crawler 2, a guide wheel 3, a baffle plate 4, a supporting wheel 5, a supporting wheel 6, Speed detection disc 7, drive wheel 8 and hydraulic motor 9.

The vehicle frame 1 is a side beam structure, which is composed of two longitudinal beams and two cross beams. In order to increase the load-bearing capacity of the vehicle frame 1, the cross beam adopts a U-shaped structure and connects the two longitudinal beams. For the convenience of installing other devices on the vehicle frame 1, two beams extend forward and backward respectively to form a sub-frame. In order to save material, reduce weight and improve strength and rigidity, the longitudinal beam is made into a square shape.

The walking chassis adopts a rear wheel drive form, and the guide wheels 3 are installed on the front ends of the longitudinal beams of the vehicle frame 1 (one on the left and one on the left and right) to play the role of correctly winding the crawler belt 2; Four on each side) are installed below the vehicle frame 1 longitudinal beam, which plays the role of bearing and evenly distributing the weight of the whole machine; To support the track 2 to prevent it from sagging; the driving wheel is installed at the rear end of the vehicle frame 1 (one on each side), and the teeth on the driving wheel mesh with the internal teeth of the rubber track 2 to drive the rubber track 2 around The guide wheel 3 and the driving wheel 8 are coiled to drive the machine to move; the baffle plate 4 is installed on both sides of the supporting wheel 6 and connected with the longitudinal beam of the frame 1 to prevent debris from winding on the supporting wheel 6 and play a protective role .

The rubber crawler 2 is a ring-shaped flexible belt with jointless pins formed by compounding rubber and metal or fiber materials. It is mainly suitable for the walking parts of agricultural machinery, transport vehicles and engineering machinery. The rubber crawler 2 The belt is responsible for transmitting the driving force and evenly transferring the weight of the whole machine to the ground. It has the characteristics of no damage to the road surface, small grounding specific pressure, good passability, strong off-road ability, simple structure, and no maintenance.

Described hydraulic motor 9 is fixedly installed on the rear end of vehicle frame 1 (one on each side), the output shaft of hydraulic motor 9 is connected with driving wheel 8, and the output torque of hydraulic motor 9 drives driving wheel 8 to rotate. When the left and right hydraulic motors 9 have the same steering and rotational speed, the forward or reverse motion of the chassis can be completed; when the rotational speeds of the left and right hydraulic motors 9 are different, the chassis can be rotated.

The rotating speed detecting disk 7 is installed on the driving wheel 8 and rotates synchronously with the driving wheel 8 . There are a plurality of teeth on the rotational speed detection disc 7, and the rotational speed of the rotational speed detection disc 7 is detected by a sensor, and the form speed of the chassis can be obtained through calculation.
