Abstract
The utility model relates to a disc type hydraulic brake of an automotive front wheel, which comprises a brake caliper (1), a brake caliper mounting bracket (2), a knuckle (3), an anti-splashing plate (4), a hub bearing unit and a brake disc (6). The outer ring (5-1) of the hub bearing of the hub bearing unit is provided with a bulge (5-6), the bulge (5-6) is provided with a bolt hole, the knuckle (3) is connected with the bulge (5-6) through a bolt, the inner ring (5-2) of the hub bearing is provided with a wheel bolt (5-8), and the brake disc (6) is sleeved on the wheel bolt (5-8) through a hole sleeve and is provided with a group of ventilation holes (6-1). The utility model has the advantages that: the hub bearing unit is integrated with a sealing ring component, and maintenance is avoided; the bearing clearance is controlled by a professional manufacturer, fuel consumption can be reduced, and the service life of the bearing can be prolonged; and with the ventilation structure of the brake disc, the heat dissipation of the brake is improved.
Description
Technical field
The utility model relates to vehicle front disc hydraulic break field.
Background technique
At present, traditional SUV vehicle front disc hydraulic break is mainly by brake calipers, brake caliper anchor plate, knuckle, splash-back, double row bearing, brake disc and hub unit constitute, brake calipers is installed on the brake caliper anchor plate, and brake calipers is installed on the knuckle by brake caliper anchor plate, double row bearing is by the press-fit approach knuckle endoporus of packing into, hub unit is connected with the double row bearing inner ring by press-fit approach, brake disc is installed on the hub unit wheel bolt, splash-back is installed on the knuckle, and between knuckle and brake disc, double row bearing is by bearing outer ring, bearing inner race, steel ball and retainer are formed, be provided with raceway between bearing outer ring and bearing inner race, steel ball is installed in the raceway by retainer.Owing to self do not have sealing configuration, needing increases seal ring by break producer, is difficult to reach the desirable seal effect.Existing brake structural mode deficiency is that bearing adopts finished product to press fit into knuckle endoporus mode by break producer, the play of bearing after press-fiting is difficult for guaranteeing, rotational resistance is big after causing a certain proportion of break entrucking, increases oil consumption, shortens bearing life.Brake disc is a solid construction, when braking, be converted to heat energy by kinetic energy, solid disc is unfavorable for air ventilation, heat dispersion is poor when causing braking, and in continuous braking process, braking plate, brake disc temperature sharply rise, the serious consequence that will cause braking failure under high-temperature condition can shorten brake disc, braking plate working life simultaneously.The double row bearing of tradition SUV vehicle is a tapered roller bearing, tapered roller bearing is applicable to the vehicle of heavy-duty low-speed, general load-carrying lorry, the highest design speed is about 90km/h, and the SUV design speed is more than 160km/h, and tapered roller bearing will produce a large amount of heats under high speed, and bearing temperature is sharply risen, high temperature easily makes lubricating grease thawing in the bearing, reduces lubrication effect.Liquid lubricating grease is easily revealed simultaneously, will speed up wearing and tearing when lubricating grease is not enough, and the stuck problem of may ablating.
The model utility content
The purpose of this utility model is exactly to provide a kind of vehicle front disc hydraulic break at the deficiency of traditional SUV vehicle front disc hydraulic break.
A kind of vehicle front disc hydraulic of the utility model break, it is by brake calipers, brake caliper anchor plate, knuckle, splash-back, hub-bearing unit and brake disc constitute, brake calipers is installed on the brake caliper anchor plate, and brake calipers is installed on the knuckle by brake caliper anchor plate, splash-back is installed on the knuckle, and between knuckle and brake disc, hub-bearing unit is by the hub bearing outer ring, the hub bearing inner ring, bearing, retainer and seal ring assembly are formed, between hub bearing outer ring and hub bearing inner ring, be provided with raceway, steel ball is installed in the raceway by retainer, the hub bearing outer ring of hub-bearing unit is provided with projection, projection is provided with bolt hole, knuckle is connected with projection by bolt, the hub bearing inner ring is equipped with wheel bolt, brake disc on wheel bolt, and is provided with one group of vent hole by borehole jack.
The bearing of hub-bearing unit is a deep groove ball bearing, and deep groove ball bearing is installed in the bearing race.
The utility model has the advantages that: adopt finished product to press fit into knuckle endoporus mode on bearing and change hub-bearing unit application bolt connecting mode into, bearing clearance is by bearing specialized factory control, and simultaneously integrated seal ring assembly avoids maintenance, reduce oil consumption, prolong bearing life.Have one group of vent hole on brake disc, brake disc rotates with wheel, and air flows through from vent hole during braking, and the heat that produces when taking away braking improves thermal diffusivity.
