Summary of the invention:
The purpose of this utility model provides a kind of battery-operated motor cycle servant brake eccentric cam built-up shaft, makes threaded shaft, crank throw that square shaft, cylinder axis and protruding axle are installed and is made into integral piece, with the cover plate welding or revolve riveting on cam, forms the eccentric cam built-up shaft.
A kind of battery-operated motor cycle servant brake eccentric cam built-up shaft, the eccentric cam built-up shaft is installed square shaft, cylinder axis, cam and cover plate by threaded shaft, crank throw and is formed, the threaded shaft of eccentric cam built-up shaft, crank throw are installed square shaft, the vertical part that links into an integrated entity with cam of cylinder axis, the cover plate evagination is outside cam, cover plate and cam weld or revolve riveting and link together, and form the eccentric cam built-up shaft.
The utility model battery-operated motor cycle servant brake is described as follows with eccentric cam built-up shaft structure:
Threaded shaft, crank throw are installed square shaft, the concentric shafts of cylinder axis three for vertically being connected, the threaded shaft external diameter is installed the square length of side of square shaft less than crank throw, crank throw is installed the end that square shaft is used for installing crank throw, the square opening that is crank throw one end is sleeved on the square shaft outside, and the crank throw of on threaded shaft, installing with the fastening bottom of nut, the external diameter of the cylinder axis that the square length of side that crank throw is installed square shaft is connected less than lower vertical, cartridge sleeve is contained in the lining of servant brake, vertical being connected of last plane of cylinder axis and lower cam; The lower plane of cam (being the baseplane) with its on the plane be the face of being parallel to each other, the semicircle indent welding groove of the lower plane of cam and the cover plate of bottom, oval indent welding groove be by being welded together, and the lower plane of cam also can revolve riveting lid and cover plate by the cam of cover plate bottom and revolve riveting and link together.
It is the cam rectangle sides that cam has a side, be connected with other side arc surfaces of cam by circular arc chamfering, cover plate also has a cover plate rectangle sides, logical circular arc chamfering is connected with other sides of cover plate, the cover plate rectangle sides evagination of cover plate is in the cam rectangle sides of cam, and cover plate rectangle sides and cam rectangle sides are parallel faces.
The utility model battery-operated motor cycle servant brake is easy with eccentric cam built-up shaft processing and fabricating, during cam rotation, can prevent that by cover plate shoe plate from swashing, and brakes safely and reliably when having guaranteed the brake of battery-operated motor cycle servant brake.
