Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a radiator mounting tool for elastically mounting a radiator on a vehicle body by means of a projection extending upward from the radiator and extending upward.

(Prior Art) Conventionally, as a fixture of this kind, according to Japanese Utility Model Laid-Open No. 60-46335, a bracket to be joined to a vehicle body and an elastic material having a central cylindrical portion that is externally fitted to a protrusion on the upper surface of a radiator are used. Consists of
The elastic member is fixed to the bracket at the outer peripheral edge portion of the flange portion on the outer periphery of the tubular portion, and a lightening portion is formed in the flange portion to reduce the elastic coefficient in the vertical direction of the elastic member, and thereby the radiator is used. It is known that a dynamic damper effect is obtained, and in this case, the lightening portion is generally formed over the entire circumference of the flange portion.

(Problems to be Solved by the Invention) In the above-mentioned conventional technique, since the lightening portion is formed over the entire circumference of the flange portion of the elastic material, the elastic coefficient in the horizontal direction of the elastic material also becomes small and the vehicle suddenly moves. When braking or suddenly starting, the radiator may shake too much in the front-back direction.

An object of the present invention is to provide a fixture that solves such problems.

(Means for Solving the Problems) The present invention provides a radiator mounting tool for elastically mounting a radiator on a vehicle body at an upwardly protruding projection provided on an upper surface of the radiator in order to achieve such an object. A bracket coupled to the vehicle body, and an elastic member having a central cylindrical portion that is fitted onto the protrusion, and the elastic member is fixed to the bracket at the outer peripheral edge portion of the flange portion on the outer periphery of the cylindrical portion, In the case where the lightening portion is formed on the flange portion, the lightening portion is formed only on portions on both sides in the vehicle width direction with respect to the tubular portion of the flange portion, and the lightening portion is formed on a central portion in the longitudinal direction of the lightening portion. It is characterized in that a stopper portion is formed which bulges into the cutout portion to sandwich the width of the cutout portion.

(Embodiment) The present invention will be described with reference to the illustrated embodiment.

In the drawings, (1) shows a radiator, and (2) shows an automobile body. The radiator (1) is formed on a top surface of the radiator by a pair of left and right protrusions (1a) (1a) extending upward from the radiator (1). The bulkhead door upper frame (2a) at the front of 2) is elastically attached via each attachment (3). More specifically, as shown in FIGS. 4 and 5, each of the fittings (3) has a cylindrical bracket (4) having a flange (4a) on the upper portion and an outer portion on the protrusion (1a). It is composed of a rubber or other elastic material (5) consisting of a central tubular portion (5a) to be fitted and a flange portion (5b) on the outer periphery of the tubular portion (5a), and the elastic material (5) is used for the flange portion. At the outer peripheral edge of (5b), it is fixed to the lower side of the cylindrical portion (4b) of the bracket (4) by baking binding or the like, and as shown in FIG. 3, the bulkhead upper frame (2a) Insert from the pair of left and right through holes (2b) opened on the upper surface, fit the tubular portion (5a) onto the respective projections (1a), and attach the bracket (4) to the flange (4a). The upper surface of the frame (2a) is screwed by a pair of bolts (6) and (6).

Further, a thinned portion (7) is formed on the flange portion (5b) of the elastic material (5) of each of the fittings (3) to reduce the vertical elastic coefficient of the elastic material (5) to reduce the radiator (5). The dynamic damper effect according to 1) is obtained.

As shown in FIGS. 1 and 3, the lower side of the radiator (1) has a pair of left and right pins (1b) protruding from the lower surface of the radiator (1) of the bulk head drawer frame (2c) of the vehicle body (2). The rubber (8) on each of the pair of left and right brackets (2d) protruding from the back was fitted and supported. Here, according to the present invention, the lightening portions (7) are formed only on portions on both sides in the vehicle width direction with respect to the tubular portion (5a) of the flange portion (5b) of the fixture (3). In the case shown in the figure, the lightening portion (7)
As clearly shown in FIG. 4 and FIG. 5, a range of approximately 120 ° from the center of the tubular portion (5a) in each part of the flange portion (5b) on both sides in the vehicle width direction with respect to the tubular portion (5a). And a stopper portion (7a) consisting of a protruding protrusion protruding into the through hole is provided at the central portion in the longitudinal direction of each of the through holes. The central portion in the longitudinal direction was formed to have a width narrower than both ends. Further in the illustration,
The outer peripheral edge portion (5c) of the flange portion (5b) of the elastic material (5) is
The lower end of the cylindrical portion (4b) of the bracket (4) is formed into a tubular shape so as to wrap it from below, and a suitable place around the lower end of the cylindrical portion (4b), for example, both lateral sides are bent outward.
The elastic material (5) and the bracket (4) are bound so that the bent portions (4c) (4c) are also wrapped, and the bracket (4) is bound by the both bent portions (4c) (4c). The elastic member (5) can be prevented from coming off from the radiator (1), and the radiator (1) can be prevented from vibrating in the vertical direction by the radiator (1).
When the upper surface of the outer peripheral edge portion (5c) hits the lower end of the outer peripheral edge portion (5c), the contact force is applied to the lower end of the bulging portion (5d) on the outer side of each bent portion (4c) of the outer peripheral edge portion (5c). In order to improve the durability of the elastic material (5), the elastic material (5) can be received over a relatively wide area.

(Operation) By elastically attaching the radiator (1) to the vehicle body (2) through the fixture (3), the radiator (1) functions as a dynamic damper, and low frequencies generated in the vehicle body (1). Vibration is effectively suppressed. Here, the lightening portions (7) formed on the elastic material (5) of the attachment (3) are provided on both sides in the vehicle width direction with respect to the tubular portion (5a) of the flange portion (5b) of the elastic material (5). By forming only the elastic member, the elastic coefficient of the elastic member (5) in the front-rear direction does not decrease unlike the conventional one. Therefore, excessive swaying of the radiator (1) in the front-rear direction, which occurs when the vehicle is suddenly braked or suddenly started, is prevented.

Further, when the radiator (1) rolls in the vehicle width direction to some extent, the opposite sides of the lightening portion (7) come into contact with the stopper portion (7a), and further rolling is restricted, and the radiator (1)
It also prevents the car from shaking too much in the width direction. It is also conceivable to form the lightening portion (7) in the shape of a narrow slit in order to regulate the rolling of the radiator (1), but this is done in the vertical vibration of the radiator (1). Concentrated stress acts on both ends in the longitudinal direction, cracks are easily formed on both ends, and durability deteriorates. On the other hand, in the present invention, only the central portion in the longitudinal direction of the lightening portion (7) forming the stopper portion (7a) is narrowed, and both ends of the lightening portion (7) are widened. As a result, concentrated stress is less likely to act and durability is improved.

(Effect of the Invention) As described above, according to the present invention, the lightening portions are formed only on both sides in the vehicle width direction with respect to the tubular portion of the flange portion of the elastic material, and the radiator is effectively used as a dynamic damper. It is possible to prevent the radiator from swaying too much in the fore-and-aft direction when the vehicle is suddenly braked or suddenly started without impairing the function of the fixture, and a stopper portion is formed at the center of the lightening portion in the longitudinal direction. By doing so, it is possible to prevent the radiator from swinging too much in the vehicle width direction, and to prevent the durability from being lowered due to the action of the concentrated stress on both ends of the lightening portion.
