Abstract
The utility model relates to a hub unit of a wheel type engineering machine chassis, wherein a walking part of a wheel type engineering machine is provided with a hub unit assembly with a heavy-type tapered roller bearing, wherein an axle of the hub unit assembly can be connected with a suspending component of the engineering machine chassis, and a shell of the hub unit assembly can be connected with a rim of a vehicle wheel, so that the vehicle wheels of the wheel type engineering machine are connected with the shells of the hub units through the rims of tires and can rotate around the axles through the bearings; however, the axles are connected with the suspending component of the wheel type engineering machine chassis so as to be capable of bearing the weight of the wheel type engineering machine chassis; and in addition, the hub unit utilizes the heavy-type bearing so as to be capable of greatly meeting the use conditions of engineering vehicles under various environments of construction sites and to ensure the reliability of the hub unit in use.
Description
Technical field
The claimed technology of this patent belongs to technical field of engineering machinery.
Background technology
The market field of application of industrial wheeled equipment is very extensive, can be widely used in the various construction operations in indoor and outdoor places such as various building ground, harbour, town road, square, container depot, goods yard, parking area, airfield runway.Chassis as industrial wheeled equipment, normally adopt the general-utility car chassis, because traditional automobile hub unit is primarily aimed at the design of over-the-road transportation vehicle, can not adapt to the usage condition of engineering truck under the environment of various building sites well, poor reliability, damageable defective have occurred.For industrial wheeled equipment is reliablely and stablely worked in the construction operation process, this patent has been invented a kind of hub for wheel type engineering machinery chassis.
Summary of the invention
This patent has designed a kind of hub of wheel type engineering machinery chassis.Comprise enclosing cover screw (1), outer cover plate (2), circular nut (3), bearing (4), hub shell (5), axletree (6), inner cap screw (9), inner cover plate (10), dust ring (11), described outer cover plate (2) is installed on the described hub shell (5) by described enclosing cover screw (1), described axletree (6) is installed in the described hub shell (5) by described bearing (4) and circular nut (3), described hub shell (5) is installed on the described wheel rim (8) by described wheel rim screw (7), described axletree (6) is installed in described chassis by described hanging screw (12) and hangs on (13), the described heavy serial tapered roller bearing (4) of two positioned opposite is installed in the described hub shell (5), make that wheel can bearing radial force, axial force and axial moment of flexure, the axis direction of described axletree (6) is separately installed with described outer cover plate (2) and inner cover plate (10), and described dust ring (11) is installed to prevent silt in described inner cover plate (10), dust enters bearing track, the aggravation wear-out of a bearing.Namely at the crawler body of industrial wheeled equipment, design a hub assembly that has heavy serial tapered roller bearing, the axletree of hub assembly can link with the sprung parts of engineering machinery chassis, hub assembly shell can link with the wheel rim of wheel, therefore, the wheel of industrial wheeled equipment connects with the hub shell by the wheel rim of tire, can rotate around axletree by bearing, and axletree connects the chassis weight that can support industrial wheeled equipment with the wheel type engineering machinery chassis sprung parts, because hub has adopted heavy serial bearing, therefore can adapt to the usage condition of engineering truck under the environment of various building sites well, guarantee hub reliability in use.
Description of drawings
Fig. 1 is a kind of hub assembly drowing of wheel type engineering machinery chassis.
The specific embodiment
Below in conjunction with accompanying drawing, describe a kind of specific embodiment of the hub for wheel type engineering machinery chassis in detail.
As shown in Figure 1, a kind of hub for wheel type engineering machinery chassis comprises enclosing cover screw 1, outer cover plate 2, circular nut 3, bearing 4, hub shell 5, axletree 6, inner cap screw 9, inner cover plate 10, dust ring 11.Described outer cover plate 2 is installed on the described hub shell 5 by enclosing cover screw 1.Described axletree is installed in the described hub shell 5 by described circular nut 3 and described bearing 4, described inner cover plate 10 is installed on the described hub shell 5 by described inner cap screw 9, described hub shell 5 connects with described wheel rim 8 by described wheel rim screw 7, and described axletree 6 hangs 13 by described hanging screw 12 and described chassis and connects.
As shown in Figure 1, the wheel of industrial wheeled equipment connects with described hub shell 5 by the wheel rim 8 of tire, can rotate around described axletree 6 by described bearing 4, and described axletree 6 connects the chassis weight that can support industrial wheeled equipment with described wheel type engineering machinery chassis sprung parts 13, owing to hub has adopted described (heavy series) bearing 4, therefore can adapt to the usage condition of engineering truck under the environment of various building sites well, guarantee hub reliability in use.
