Both ends are connected by a pin shaft, and a second connecting device and the pin shaft are provided with grease holes, so that grease can be injected for lubrication, the abrasion is reduced, and the prior dry friction is changed into the prior sliding friction; because the second connecting device is not abraded, the position between the oil cylinder and the second connecting device is relatively fixed, so that the swing of the front axle can be more accurately controlled, and the overall performance of the excavator is improved.
Description
Technical Field
The utility model relates to a wheel-type is suspension cylinder technical field for the machine that digs specifically is a new connection form of suspension cylinder for wheel-type is digged machine.
Background
At present, a wheel type excavator generally adopts a structural form that a piston rod of a suspension oil cylinder is pressed on a supporting seat of a front drive axle (the attached figure of an original connecting structure is shown in figure 1), and as shown in the attached figure of the original connecting structure, a right suspension oil cylinder 1, a lower frame welding assembly 2, a left suspension oil cylinder 3, a supporting seat 4 (2 pieces) and a front drive axle 5 are assembled. When the front drive axle of the excavator during walking swings or the suspension oil cylinder is locked during working, the suspension oil cylinder is subjected to axial force and horizontal force according to acting force and reacting force, so that friction between the piston rod and the guide sleeve can be increased, and after the excavator works for a period of time, the clearance of a sealing element of the oil cylinder is too large, and oil leakage of the oil cylinder can occur. In addition, the friction between the piston rod of the suspension oil cylinder and the support seat of the front drive axle is dry friction, the support seat is seriously abraded due to long-time work, the working performance is influenced, the support seat needs to be replaced in time, and the cost is correspondingly increased. Therefore, a new connecting form of the suspension oil cylinder for the wheel excavator is provided.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a new connected form of suspension cylinder is used to wheeled excavator to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a wheeled excavator is with hanging hydro-cylinder new connection form, includes frame welding assembly down, frame welding assembly's both ends are connected through connecting device one respectively and are hung the hydro-cylinder down, connecting device one includes two sets of supports that are located respectively and hang the hydro-cylinder left and right sides, the support passes through bolt fixed connection frame welding assembly down, and just two sets of supports rotate through the round pin axle with hanging the hydro-cylinder and be connected the hydro-cylinder other end and all be connected with preceding drive axle through connecting device two, connecting device two includes the fixed plate, be equipped with two sets of connecting blocks on the fixed plate, two sets of connecting blocks are connected through the round pin axle with the one end of hanging the hydro-cylinder, the fixed plate passes through 4 bolt fastening on the front drive axle.
Furthermore, the first connecting device and the second connecting device are both provided with oil holes.
Compared with the prior art, the beneficial effects of the utility model are that:
1. when the front drive axle of the excavator during walking swings or the suspension oil cylinder is locked during working, the suspension oil cylinder also swings by a corresponding angle, so that stress is always transmitted to the frame along the direction of the piston rod, friction between the piston rod and the guide sleeve is reduced, and the oil leakage phenomenon is well solved;
2. one end of the suspension oil cylinder is connected with the lower frame welding assembly, and the other end of the suspension oil cylinder is connected with the front drive axle through a second connecting device. Both ends are connected by a pin shaft, and a second connecting device and the pin shaft are provided with grease holes, so that grease can be injected for lubrication, the abrasion is reduced, and the prior dry friction is changed into the prior sliding friction;
3. because the second connecting device is not abraded, the position between the oil cylinder and the second connecting device is relatively fixed, so that the swing of the front axle can be more accurately controlled, and the overall performance of the excavator is improved.
