Abstract

The utility model discloses a motor and hydraulic pump mounting structure on hybrid excavator belongs to engineering machine tool technical field. The hydraulic excavator overcomes the defects that in the prior art, the motor and the hydraulic pump in the hybrid power hydraulic excavator are mounted on an engine, so that the suspension of the motor and the hydraulic pump is too long, the axial mounting length is too long, and the arrangement space is limited. The mounting seat comprises a base fixedly connected with the frame, vertical plates are fixedly mounted on two sides of the base respectively, the vertical plates on two sides are fixedly connected with the motor and the hydraulic pump respectively, a protective cover is mounted between the vertical plates on two sides, and the shaft coupling is arranged in the protective cover.

Description

Motor and hydraulic pump mounting structure on hybrid excavator

Technical Field

The utility model belongs to the technical field of the engineering machine tool, specifically speaking especially relates to a motor and hydraulic pump mounting structure on hybrid excavator.

Background

With the requirements of economic development and environmental protection, green energy and energy conservation become more and more important, and hybrid power becomes a new development direction of the hydraulic excavator in the field of engineering vehicles.

The hybrid power system of the hybrid hydraulic excavator is generally provided with a first power source engine, a second power source motor and a third power source hydraulic pump, the mounting structure of the hybrid hydraulic excavator is generally an arrangement mode that three power sources (including the engine, the motor and the hydraulic pump) are axially connected in series, the mounting point of the hybrid hydraulic excavator and a frame is completely located on the engine, and the motor and the hydraulic pump are sequentially fixed with the engine and suspended on the engine and are not fixedly connected with the frame. Because the mounting point is all located engine one side, it is big to cause driving system to arrange the length in engine axial direction, arranges the space limited, and the motor is longer with the hydraulic pump suspension, makes each connecting bolt atress increase to cause the bolt fracture easily, and then lead to motor and hydraulic pump to drop, poor stability more can not satisfy the balanced requirement of hydraulic shovel hybrid power system during operation.

Disclosure of Invention

The utility model aims at providing a motor and hydraulic pump mounting structure on hybrid excavator to install the motor that causes motor and hydraulic pump suspension overlength, axial installation length too big and arrange the limited defect in space on the engine with hydraulic pump among the overcome prior art among the hybrid excavator.

The utility model discloses an adopt following technical scheme to realize: the utility model provides a motor and hydraulic pump mounting structure on hybrid excavator, includes frame, hydraulic pump and motor, and motor and hydraulic pump pass through the coupling joint, still include the mount pad, the mount pad include with frame fixed connection's base, base both sides respectively fixed mounting riser, both sides riser respectively with motor and hydraulic pump fixed connection, install the safety cover between the riser of both sides, the shaft coupling is in the safety cover.

Further, at least one shock absorber is arranged between the base and the frame.

Further, the number of the dampers is four.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model has the advantages that the installation seat is arranged, so that the motor and the hydraulic pump in the hybrid power excavator are prevented from being suspended on the engine, and the problems of overlong axial length of the engine and limited arrangement space are solved; the motor and the hydraulic pump are respectively suspended on two sides of the mounting seat, so that the overlong suspension of the motor and the hydraulic pump is avoided, and the problems that the connecting bolt is stressed greatly and is easy to break due to the overlong suspension of the motor and the hydraulic pump are solved.

2. Set up the shock absorber between mount pad and the frame, improved whole driving system's stability.
