Description
Technical field
The present invention relates to the brake beam technology, relate in particular to a kind of rolling stock brake beam.
Background technology
At present, bogies for railway vehicles adopts the brake equipment of lever form usually, this brake equipment mainly comprises brake beam, middle pull bar, truck dead lever, floating lever etc., wherein, brake beam is the braking force that is used for the car body transmission, mean allocation is given the brake shoe at its two ends, so that brake shoe is abutted on the wheel, thereby relies on the friction between brake shoe and the wheel to realize vehicle braked.
Fig. 1 is the front view of existing rolling stock brake beam; Fig. 2 is the birds-eye view of existing rolling stock brake beam; Fig. 3 is the perspective view of existing rolling stock brake beam.As Fig. 1, Fig. 2 and shown in Figure 3, existing rolling stock brake beam is the L-B composite brake beam, comprise brake beam frame 10, these brake beam frame 10 integral body are hollow structure, brake beam frame 10 is between the middle part of hollow and is connected with pillar 20, brake beam frame 10 two ends are symmetrically arranged with brake head 30, and brake beam integral body is horizontal structure; The middle part of pillar 20 is provided with the brace groove 201 that is connected and is suitable for the brake lever rotation with brake lever, and longitudinal center's face of brace groove 201 and car body is certain angle r.This brake beam can be used for being connected with hand brake lever with the brake cylinder of brake equipment, is used for power is delivered to brake head, realizes the braking to car body.
But, existing rolling stock brake beam can not adapt to and satisfy the needs of assembling brake cylinder and hand brake lever, adopt when having brake beam now, brake cylinder in the brake equipment and hand brake lever can only be installed on the car body, therefore, must be equipped with on the car body and adapt to brake cylinder and accessories such as hand brake lever bonded assembly lever, tie rod, pipe hang, carriage, make that brake equipment weight is big, inconvenience is installed, and car body underframe space is limited, brake cylinder and hand brake lever is installed will be caused the vehicle body space anxiety.In addition, when brake cylinder and hand brake lever are installed on the car body, can make whole brake equipment have more power and transmit lever that it is more that power is transmitted node, causes the power transmission efficiency of brake equipment lower, influences the deceleration and stopping performance of brake equipment; And, when brake cylinder and hand brake lever are installed in car body, owing to be subjected to the influence of the structure of car body, brace groove on the pillar of brake beam need have certain angle just can realize the motion of hand brake lever with longitudinal center's mask of car body, thereby cause in the whole brake equipment the part parts can with longitudinal center's face of car body towards lopsidedness, this inclination is very easily under braking and relieved state, cause brake beam to be subjected to one along the transverse force effect of cross-car and amesiality, thereby influence the braking effect of whole brake equipment.
To sum up, existing rolling stock brake beam structure can't adapt to the installation of brake cylinder and hand brake lever in the brake equipment, make brake cylinder and hand brake lever have to be installed on the car body, and brake cylinder and hand brake lever are when being installed in car body, can cause the power transmission lever of brake equipment more more with power transmission node, the power transmission efficiency of brake equipment is relatively poor, influences the deceleration and stopping performance of brake equipment, and is unfavorable for the installation of the parts of brake equipment.
