Abstract

The utility model discloses a four-axis locomotive bogie, which is formed by two symmetrically arranged front and rear two-axis bogies and a middle framework, wherein in each two-axis bogie: two ends of a W-shaped framework are crossed under a front-rear wheel sat and a shaft box, and the W-shaped framework utilizes a secondary rubber pile to form a support for the middle framework; the middle framework is provided with a damping mechanism connected with a locomotive base frame on the upper part of the four-axis bogie; and along a rail direction, and the W-shaped framework is provided with a single push-pull traction rod which is connected with a locomotive body traction seat. According to the four-axis locomotive bogie, the framework is arranged under the shaft boxes, so that the installation height of the middle framework of the bogie is reduced, a B0B0-B0B0 axial eight-axis locomotive can be realized in Chinese standard track gauge limit. Simultaneously, due to low traction of the single rod, the structure is simplified, and higher adhesion availability can be obtained.

Description

Four engine trucks
Technical field
The utility model patent belongs to railway locomotive, especially heavy loading locomotive bogie truck manufacturing technology field.
Background technology
The principal mode high-power locomotive of China's freight shipments is the AC transmission electric power locomotive of shp 9600kW, 2C0 shaft type at present, and its curving performance is relatively poor, the mountain route that the incompatibility radius of curve is less.Eight locomotives of single-unit can improve the traction tonnage of wheel rail adhesion weight and single-unit locomotive effectively.Six locomotives of domestic relatively 2C0 shaft type 9600kW just under arms, it is big to have an adhesion weight, permanent merit wide ranges, the advantage that curving performance is good.Domestic relatively two-shipper heavily joins eight locomotives, has to make and the low advantage of maintenance cost.Eight locomotives of B0B0-B0B0 shaft type have good straight line dynamic performance and curving performance; Also a kind of feasible mode on its structure, like type locomotive of the former Soviet Union.B0B0-B0B0 shaft type locomotive is made up of two four-shaft steerings and a car body.The four-shaft steering locomotive adopts three to be suspension, by intermediate frame two group of 2 axle bogie is connected into a four-shaft steering.When locomotive passes through curve, because eight axles of locomotive all can bear the wheel track transverse load, can improve the locomotive curving performance greatly, this is that 2C0 shaft type locomotive and 3B0 shaft type locomotive are too far behind to catch up.Three of locomotive is can decay the effectively vertical and lateral vibration of wheel track operation of suspension, makes driver's cab obtain the good comfort index.The four-shaft steering technical barrier of eight locomotives of Chinese Industrial Standards (CIS) gauge single-unit is: this engine truck adopts three to be suspension, makes that the plane height to the top of rail is higher on the bogie truck, influenced by the locomotive height gauge and is difficult to realize.
The utility model content
Above shortcoming in view of prior art; The purpose of the utility model provides a kind of bogie truck that is installed in the below of axle box; Reduce the last level of bogie truck intermediate frame, eight locomotives of B0B0-B0B0 shaft type are achieved in Chinese Industrial Standards (CIS) gauge gauge also can make this locomotive realize good straight line and curve motion quality.
The purpose of the utility model is to realize through following means.
Four engine trucks are made up of two axle truck and intermediate frame that former and later two symmetries are placed; In each two axle truck: the across of W shape framework front and back wheel to axle box below, W shape framework utilizes two, and to be rubber metal pad become to support to middle framework shape; Intermediate frame is provided with the car body underframe bonded assembly damper mechanism that is used for four-shaft steering top; On direction along ng a path, said W shape framework is provided with singly recommends draw bar and is connected with the car body traction seat.
Adopt structure as above, the utility model is installed in the below of axle box with framework, thereby reduces the setting height(from bottom) of bogie truck intermediate frame, and eight locomotives of B0B0-B0B0 shaft type are achieved in Chinese Industrial Standards (CIS) gauge gauge.Simultaneously, owing to adopt three to be suspension type, can make this locomotive realize good straight line and curve motion quality.
Description of drawings
Fig. 1 is the four-shaft steering front view.
Fig. 2 is the framework left view.
Fig. 3 is the framework birds-eye view.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the structure of the utility model is described further.
Among the figure, the 1-wheel is right, 2-axle box structure, 3-W shape framework, 4-motor; 5-Z shape draw bar, 6-two is a rubber metal pad, the 7-intermediate frame, 8-car body traction seat, 9-three is a vertical damper; 10-one is a vertical damper, and 11-three is a spring, the 12-lateral damper, and 13-one is a spring.
Can see each position component relation of the utility model in conjunction with Fig. 1 Fig. 2 and Fig. 3, the utility model is made up of two two axle trucks and intermediate frame 7, and two axle truck is made up of with W shape framework 31 wheel.Wheel comprises that through single stage suspension axle box 2 and is that vertical damper 10 is connected with 3 of W shape frameworks to 1.The two ends of W shape framework 3 are installed in the below of axle box structure 2.Motor 4 adopts the seize suspension, and the other end is hung on W shape framework 3.W shape framework 3 utilizes two to be that rubber metal pad 6 supports intermediate frame 7.Intermediate frame 7 is that spring 11, three is that vertical damper 9 and three is that lateral damper 12 is connected with the car body underframe on four-shaft steering top through three.At direction along ng a path, W shape framework 3 is singly recommended draw bar 5 through two and is drawn to the four-shaft steering middle part, is connected with car body traction seat 8, transmits wheel track longitudinal traction power and braking force.The two ends of draw bar are equipped with the elastic caoutchouc joint, with movement relation and the stressed relation that adapts to bogie truck.The same seize hang that adopts with prior art of the installation of motor, its other end is hung on framework, in this programme, promptly hangs on W shape framework.
The utility model structure is through reduce the height of four-shaft steering effectively, and eight high-power locomotives of single-unit that can satisfy the B0B0-B0B0 shaft type of Chinese vehicle gauge of the locomotive are achieved, and can make this locomotive realize good straight line and curve motion quality.
