Abstract
The invention discloses an intermediate transmission shaft supporting assembly for a heavy-duty vehicle. The intermediate transmission shaft supporting assembly comprises a connecting plate, a buffer disc arranged on the connecting plate, a bearing block fixed in the buffer disc and a bearing arranged in the bearing block, wherein the connecting plate comprises a U-shaped main body plate; the inner side face of the U-shaped main body plate is provided with a U-shaped groove; two ends of the U-shaped main body plate are provided with connecting holes; and the buffer disc is arranged in the U-shaped groove of the connecting plate. By adoption of the connecting plate with a special structure, the buffer disc can be firmly arranged in the connecting plate and is prevented from axially jumping due to shock, the stability is high, and the transmission stability of the transmission shaft is improved.
Description
Technical field
The present invention relates to a kind of heavy motor vehicle accessory, particularly a kind of heavy motor vehicle is used the tween drive spindle support assembly.
Background technology
The center support assembly is the key component that tween drive spindle is formed.Existing center support assembly structure is unstable, causes transmission shafts to jumping easily, and adds the oiling structure, has increased the upkeep cost of vehicle, uses comparatively inconvenient; Its hermetically-sealed construction is undesirable, is prone to cause the bearing undue wear, causes bearing failure, influences the cruising of vehicle.Therefore, existing center support assembly can not be applicable to the abominable applying working condition of heavy-duty commercial vehicle.
Summary of the invention
The technical matters that the present invention will solve is: provide a kind of heavy motor vehicle of good stability to use the tween drive spindle support assembly.
In order to solve the problems of the technologies described above; The present invention includes connecting panel, be arranged on buffer disk on the connecting panel, be fixed on the bearing seat in the buffer disk and be arranged on the bearing in the bearing seat; Described connecting panel comprises the U-shaped main board; The medial surface of U-shaped main board has the groove of U-shaped, and the two ends of U-shaped main board are provided with connecting bore, and the buffer disk seat is in the U-shaped groove of connecting panel.
For preventing the buffer disk wearing and tearing, two trough rims of described groove are the chimb that the Width cross section is an arc.
In order to prevent the buffer disk bob; The upper end of described buffer disk is provided with upper plate; The middle part of upper plate is embedded in the buffer disk; The two ends of upper plate are provided with connecting bore, the two end cap of upper plate on the two ends of the U-shaped main board of connecting panel, two connecting bores on two connecting bores of upper plate and the U-shaped main board of connecting panel one by one over against.
In order to improve leak tightness; Reduce wear-out of a bearing, described bearing is an oilless metal, is equipped with seal ring in the two ends of bearing seat; Bearing is between two seal rings; The outside of each seal ring all is provided with dust-blocking ring, and dust-blocking ring comprises the flange part that propeller shaft tube is outer with being buckled in seal ring, and axle sleeve and flange partly link into an integrated entity.
The invention has the beneficial effects as follows: the present invention adopts the connecting panel of special structure, makes that buffer disk can firm being arranged in the connecting panel, can be because of not taking place axially to jump to shaking, and good stability has improved the transmission shaft stability of transmission.
